Origin & Breeding History: 'Orange Field' originated from a cross between two unnamed bistort selections, made in 2001 in Oedelem, Belgium. The objective of the breeding program was to create new bistort varieties with improved floral colours and good plant habits.
Tests & Trials: Trials were conducted during the summer of 2009 in Oxford Station, Ontario. Eleven plants of 'Orange Field' and fifteen plants of 'Blackfield' were grown in 15 cm pots in a polyhouse. Plants were spaced approximately 60 cm apart. Observations and measurements were taken on 10 plants of each variety. Colours were determined using the 2001 Royal Horticultural Society (RHS) Colour Chart.
